Application filed August 23,

This invention relates to a bracelet end hook for detachably securing the endsof a flexible bracelet to the bails or lugs of a wrist watch andhas for its object to provide an end hook having a tongue for closing the opening to the hook with means for retaining the tongue in open position while the hook is being attached to or detached from the bails of a wrist watch.

A further objectof this invention is to provide a latch part on the tongue which will engage a suitable formation on the shank of the hook to hold the tongue in open position until manually released.

\Vith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully de scribed, and particularly point-ed out in the appended claims.

In the accompanying drawings:

Figure 1 is a top plan view of a wrist watch with a. bracelet secured thereto by my improved end hooks.

Figure 10 is a perspe her for positioning an spring in the body. It is often foun press the tongue of the wardly to open the ho time detach the hook wrist watch, and in order to simplify the manual manipulation for this purpose, I have provided a construction by which the the abut ctive view of memd centralizing the d in practice difficult to bracelet end hook inok and atthe same from the bail of a the inherent tension of the stock tending to 1927. Serial No. 214,883.

tongue will remainin open posit-ion while the end hook-is being detached from the watch, the same consisting of a latch mountedon the tongue to extend through an openmg in the shank of thehook and snap over the edge of the opening whichlatch may be released by pressure on its end to permit the hook to spring back by its inherent ten- S1011 into engagement with the inner surface of the hook to close the opening thereto, and the following is a detailed description of the present embodiment of this invention illustrating onemeans by which these advantageous results may be accomplished.

lVith reference to the drawings 10 designates the body of the end hook having a top plate 11 with sides 12 folded therefrom and bent inwardly to provide flanges 13 which are also turned upwardly to form lips 14: to provide a rest for the abutment of the spring. A; slide 15 is mounted in the body 10 which has a shank portion 16 formed into a hook 17 at one end. This hook is closed by a resilient tongue 18 which engages the inner surface of the hook 17 by 30 force the tongue in this direction.

. The shank portion 16 is pierced or provided with an opening 19 in its top wall through which a latch part 20 carried by V the tongue may extend when the tongue is moved to open position as illustrated in Figure 8 and a detent 21 which is formed on this latch part snaps over the edge 22 of the opening 19 to retain the tongue in open position against its inherent closing tension to permit the bail 28 of the wrist watch to be removed from the hook. When it is desired to release the tongue from this open position, it is merely necessary to press on the end 24; of this latch part to' force the same toward the bend of the hook thereby releasing the detent 21 and permitting the tongue to close by the inherent tension of its stock.

A spring 25 is positioned between the folded end 26 of the slide 15 and an abutment 27 extending between the lip portions 14 against which the spring 25 acts to move the slide 15 into the body 10 to its contracted position. A bar 28 having a portion to enter 5 the coils ofthe spring is positioned at the fold 26 to centralize the spring and prevent it from moving out of alignment.

Sides 30 may he provided along the edges of the shank 16 to give a more finished appearance to the end hook and also serve the purpose of guiding the bail in its detachment from the hook and for cooperating with the latch part for preventing the hail from moving heneath the tongue and ohstrncting its opening movement thereof.

A bar Qt) connects the sides 12 of the body for attaching the hook to an adjacent bracelet link.

I have illustrated an end hook of a construction to permit extension between the hodv and hook proper. hut it will be apparent that the construction by which the tongue is held in open position will operate fully as well in a construction of an end hook which has no extendibility.

The. foregoing description is directed solely towards the construction illustrated, hut I desire it to he understood that I reserve the privilege of resorting to all the mechanical changes to which the device is suseeptihle. the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A bracelet end hook comprising a hody, a sheet metal shank with an opening therein extending from the hody, said shank being formed into an open hook at its end, a sheet metal tongue for engaging the inner surface of said hook and closing the opening thereto by the inherent tension of its stock, a latch part on said tongue for extending through the opening in said shank and a detent on said latch part to snap over the edge of said opening and hold said tongue in open position.

2. A hracclet end hook comprising a body, a sheet metal ln'oadshank extending therefrom with an opening therein and having a hook shaped end. a tongue for closing said hook end. and a latch portion carried hy said tongue for extending through the opening in said shank and snapping over the. edge of said opening for retaining the tongue in open position, said hitch heing released by manual pressure on the end protruding through the opening in said shank.

3. A hracelet end hook comprising a body, a sheet metal shank with an opening therein extending from the hodv. said shank heing formed into an open hook at its end. a sheet metal tongue for engaging the inner surface of said hook and closing the openin; thereto hy the inherent tension of its stock. an integral latch part hent from the edge of said tongue for extending through the opening in said shank and an integral detent raised from the stock of said latch part to snap over the edge of said opening and hold said tongue in open position.
